Triangle A is rotated 90° clockwise with the origin as the center of rotation to create a new figure. Which triangle shows the new location?

• A

• B

• C

• D

What type of transformation is this?

• Rotation

• Reflection

• Translation

• Enlargement

If the dotted figure is the image, the original figure was reflected over the ...

• x-axis

• y-axis

• rotation 180

• translation 4 left

Describe the transformation shown in the graph.

• Reflect over x-axis
• Reflect over y-axis
• Rotate 270 degrees CCW
• Rotate 90 degress CCW

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

If you were to rotate ABCD 180°  about the origin, what would the coordinate of A' be?

• (-5, 5)

• (-5, 3)
• (-3, 3)

If you were to rotate ABCD 90° counterclockwise about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, 5)
• (-5, 3)
• (-3, 3)

Triangle ABC is going to be translated. Where would  A' position be at, if the translation was be (x,y) --> (x+3, y-2)?

• (-1,3)
• (5,3)
• (5,8)
• (3,5)
